|  Thoughts on this.
Now I know everyone runs high end ESC's. I was looking around Hobby Partz last night and ran across a brushless ESC for like 20 bucks. If i'm not build a comp truck, and trying to be money tight just to see how reasonable I can build a truck. (mainly for customers) What would be the main trouble with using one? What are the spec that need to be looked at? Like amps and that stuff? I dont have the link cause im at work. I will post it up when I get home tonight. But its a 1/18th scale brushless esc with drag brake and it has different settings to use. Thanks. |

While I'm not using one on my MRC, I am using a 35A HobbyWing ESC with a Holmes Hobbies Revolver Black in my 2.2 comp crawler. It has done everything so far that I have wanted it to. Just be sure to get the program card as well...it makes programming the ESC a breeze.

Yeah I will have to check into that. My main concern was the amperage. I think there were two different ones. |

But there has to be a reason why no one uses it.

Yes, sensored brushless systems have better low end control.

Why not just get a Sidewinder and cheaper brushed motor?

Probably what im gonna do. I was just looking into that 14 dollar brushless motor Im checking out all options. See in my town we have no LHS. Im trying to build it reasonable so I can sell some to other people. If I build one and people like it then I can sell it easier. |

Since we are now speaking of Sidewinders, here's what I have in my MRC. I am using a Sidewinder Micro along with the following outrunner. http://www.hobbypartz.com/75m60-heli...08-3500kv.html It's a great motor that will deliver both torque AND a surprising amount of wheel speed. I used the Losi pinion that came with the Pro Roller and this little combo will scoot when the throttle is mashed. Before I purchased it, I spoke with a friend of mine...Mr. JohnRob Holmes of Holmes Hobbies. He recommended that I go with a high KV motor. And, with outrunners, you have a lot more torque when going slow, as compared to an inrunner. Now, there are a couple of catches. First, the motor's shaft is 2.5mm, so the Losi pinion will have to be bored out a bit. Along with that, you will need to grind a flat spot on the shaft as well. The last catch is that you will need to alter the MRC's motor plate to accept the motor's bolt pattern. I actually have an AutoCAD drawing of the motor plate with the proper holes and spacing, but have yet to find someone to machine me one. If you know of someone who could make it, I would be more than happy to send the file to you.  All total, I have about $70 in the Sidewinder Micro/outrunner combo. Set your ESC to high power on start and you'll be able to climb anything.    |

Sending the email momentarily. Thanks for checking. As for an ESC, I would recommend going with the Sidewinder Micro. It will do both brushed and sensorless brushless motors and is TINY. You can kind of see it in the first picture I posted over on the left on top of my rear upper links. |

Yeah thats what I will prolly do. I emailed the file to my guy. What thickness does it need to be? And what do I need to tell him to make it out of? |

My micrometer's battery is dead, but based upon what I was able to measure the old fashioned way, the thickness of the plate is right around 0.06" and is made out of aluminum. If you have a digital micrometer handy, you might try measuring your plate to see if I'm correct.
